In my view, this is one of the most profound unsolved mysteries of Science. How to explain the fine tuning of the Universe without recourse to saying that a God/Designer did it.
Examples of fine tuning:
We exist because of a crucial one part in a billion difference that favors matter over antimatter.
If the ratio of the nuclear strong force to the electromagnetic force had differed by 1 part in 10 to the 16th power, no stars would have formed.
If the strong force constant were 5% weaker, there would be no stable stars
If the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds
If the expansion rate of the Universe were larger, no galaxies would form
If the expansion rate of the universe were smaller, the universe would collapse even before starts formed
If the mass density of the Universe were larger, overabundance of deuterium from the big bang would cause stars to burn rapidly, too rapidly for life to form
If the mass density were smaller, insufficient helium from the big bang would result in a shortage of heavy elements
I could go on, but lets cut to the chase.
How do you account for this:
(A) Inflation (B) Multiverse (C) Top Down Cosmology (D) God/Designer (E) Some new innovation you're working on or have that can win a Nobel Prize in Physics
Let's be clear on the options. Either we have some law that forces the fine tuning, which does not exist unless you know otherwise, or we put it to chance, which is obvious nonsense given the math, or it's a designer. Unless you have a fourth option?
